MacOS 8.1 and Mozilla/Netscape

Could anyone give me an answer to the question:

What is the latest, greatest & most stable form off Mozilla/Netscape
that can run on the MacOS 8.1 platform.

I've been asked to do anyother vounteer "how to put up a simple webpage"
class and I've always used the Composer portion of Mozilla/Netscape
because the the Mac/Linux/win32 compatibility.  The lab I'll be working
in has WIndows95/98 and Macs running MacOS 8.1 which is obviously less
than ideal :-P

The machines are all 233mhz machines and the lab is OLD but I figure I'd
still like to use the most recent version of composer that will work in
the lab.

Comments, suggestions etc etc are muchly appreciated!

Sincerely,

Christopher Lee
